You can change the default error popup that appears when something goes wrong in system texts. Also, you can create your own custom error handling system. This means that instead of showing the default popup to users, you can capture the error details and log them behind the scenes. This allows you to see more technical information about what caused the error and helps developers to identify and fix the problem. By creating your own error handling, you have more control over how errors are managed in your Mendix application.
